This book was released on 1991 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressed in this report is the problem of detecting a known signal in strong, severely non-stationary/nonhomogeneous interference of unknown statistics. Two approaches are proposed. The first one is the multiband signaling and detection scheme which makes possible a trade-off between data quantity and signal quality. Two multiband algorithms, the MultiBand Sample Matrix Inversion (MB-SMI) and Generalized Likelihood Ratio (MB-GLR) algorithms, are thus developed and shown to be able to significantly outperform the corresponding single-band algorithms, providing a potential solution to the problem which exists when the data available for learning are severely limited by the environment. To obtain the desirable CFAR feature in colored Gaussian interference at a lower computational cost, we modify the MB-SMI and obtain the MultiBand Modified-SMI (MB-MSMI) algorithm. The performance comparisons of the MB-MSMI and MB-GLR show that in Gaussian interference, the detection performance difference between the two algorithms is practically negligible and therefore, the use of the MB-GLR is unnecessary as it requires more implementation complexity. In non-Gaussian interference, however, the MB-GLR is preferable due to its much lower performance sensitivity than the MB-MSMI. To further improve the system performance, also proposed in this report is an approach which explores interference covariance structure to reduce the uncertainty in estimating unknown statistics.

Available in PDF, EPUB and Kindle. Book excerpt: In this report, which consists of two parts, the problem of radar target detection in a background of non-stationary external interference is considered. The object of the analysis is to treat this problem from the point of view of statistical decision theory, and to derive a signal processing algorithm which accepts the totality of inputs on which final decision is to be based, and performs both interference suppression and target detection. It is assumed that the radar is provided with multiple RF input channels and that target-free samples, from range gates other than one in which a target is being sought, can be used for the estimation of the interference statistics. In Part I a general formulation is given and a likelihood ratio detection rule is derived.

This book was released on 1998 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the invention of radar, each succeeding system solution has been challenged with increasing performance demands. For the last decade, added attention has been focused on lowering the life cycle cost. Sometimes new technologies and/or approaches introduce problems of their own. RADARCON presents aspects of radar technology, applications, and signal/data processing.

Download or read book Space time Adaptive Processing for Radar written by J. R. Guerci and published by Artech House. This book was released on 2003 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative, leading-edge resource gives you a comprehensive overview of sample rate conversion (SRC) and its applications in software configurable radios. The book helps you understand the limits of feasible systems for sample rate conversion, as well as the limits of interpolation. You get sound advice on selecting the appropriate types of SRC for specific applications, and assistance in handling the trade-off between hardware complexity and the clock rate of a system. From an introduction to software radio and a refresher on the fundamentals of sampling and sample rate conversion, to discussions on block signal processing and well-known and novel structures for sample rate conversion, the book offers you practical guidance that enables you to quickly find solutions for your challenging projects in the field. This first-of-its-kind reference concludes with a list of questions that - when answered - helps to design a system for sample rate conversion. Over 890 equations and 90 illustrations support key topics throughout the book.
